Microsoft Launches 'Mu,' New On-Device AI Model for Copilot+ PCs
Mu is an efficient 330 million parameter encoder-decoder language model optimized for small-scale deployment on NPUs. Its design was carefully tuned to fit the hardware's parallelism and memory limits, and ensure peak efficiency for operations. The model's development used insights gained from Microsoft's earlier Phi models and was pre-trained on hundreds of billions of high-quality educational tokens.
A development team working together to create the next version of Windows.
To enhance its performance despite having fewer parameters, Mu was fine-tuned using advanced techniques such as distillation and low-rank adaptation, and it also incorporates transformer upgrades like Dual LayerNorm, Rotary Positional Embeddings/RoPE, and Grouped-Query Attention/GQA. Initially, the Mu model will be applied to the Settings function within the Windows system, using natural language processing to convert user inputs into system commands.

Managers are using AI to determine raises, promotions, layoffs
(NewsNation) — Artificial intelligence (AI) isn't just changing workflows, it's deciding who moves up and who gets the boot. According to a new Resume Builder survey of 1,342 U.S. managers, 6 in 10 said they use AI tools to make decisions about their direct reports. Even more striking is that most managers who use AI said they've turned to it for high-stakes calls, such as determining raises, promotions and even who to let go. Yet two-thirds of those using AI admitted they haven't received training on how to manage people with it, the survey found. ChatGPT was the most popular tool among AI-using managers, with 53% citing it as their go-to. Nearly 30% said they primarily use Microsoft's Copilot, while 16% said they mostly use Google's Gemini. Other surveys have shown that managers are more likely than their employees to use AI, but the latest findings suggest a dystopian future where leadership loses its human touch entirely. 'While AI can support data-driven insights, it lacks context, empathy, and judgment,' Stacie Haller, chief career advisor at Resume Builder, warned in a statement. Haller said it's essential not to lose the 'people' in 'people management,' pointing out that AI reflects the data it's given, which can be flawed and manipulated. The concern is real enough that lawmakers have introduced legislation to limit AI's role in employment decisions. In March, a California state senator introduced the 'No Robo Bosses Act,' aimed at preventing employers from letting AI make key decisions — such as hiring, firing or promotions — without human oversight. 'AI must remain a tool controlled by humans, not the other way around,' California State Sen. Jerry McNerney, D-Pleasanton, said in a release announcing the legislation. While generative AI tools like ChatGPT and Google's Gemini have only been mainstream for a few years, they're already reshaping how people work — and how they look for work. Recent college graduates have taken notice, as the rise of AI chips away at entry-level white collar roles, helping create one of the toughest job markets in years. Meanwhile, employers are getting buried in AI-generated resumes. The number of applications submitted on LinkedIn has surged more than 45% in the past year, and the platform is now clocking an average of 11,000 applications a minute, according to the New York Times. Resume Builder's survey doesn't detail exactly how managers are using AI to automate personnel decisions. After all, there's a big difference between organizing metrics for a performance review and asking ChatGPT: 'Should I fire Steve?'

Veteran fund manager makes bold move on Apple, Marvell
Chris Versace wants to start off the holiday weekend with a blast. The lead portfolio manager for TheStreet Pro Portfolio gave readers an update on chipmaker Marvell Technology (MRVL) and computer giant Apple (AAPL) . Don't miss the move: Subscribe to TheStreet's free daily newsletter Versace said Marvell shares moved lower, following a report from The Information that said Microsoft (MSFT) intends to release its most powerful in-house AI chips in 2028 or beyond as it focuses on chips it can better develop in the interim. The report also suggested Microsoft has pushed back the release of its Maia 200 chipset to 2026 from 2025, he said. "The move lower in MRVL shares reflects that pushout, but while Microsoft is a custom AI silicon partner for Marvell, so too are Amazon (AMZN) and Meta (META) , and as we learned at the company's recent event, multiple up-and-coming hyperscalers as well," he hosted a "Custom AI" Investor Event on June 17 in New York where the company boosted its total available market to $94 billion by 2028, up 25% higher than the $75 billion by 2028 it outlined this time last year Following the pronounced run in Marvell shares, Versace said, "the same one that led us to bank some of that big move, we are not surprised that The Information's report dinged Marvell shares." More Tech Stocks: Amazon tries to make AI great again (or maybe for the first time)Veteran portfolio manager raises eyebrows with latest Meta Platforms moveGoogle plans major AI shift after Meta's surprising $14 billion move "For us, the larger story is very much intact," he said. "While the Portfolio has a full position, if the shares pulled back a bit further to the $70 level, that would fill a modest gap in the chart, and be a nice pick-up point given our $115 target." Marvell is slated to report second quarter results next month. Shares are down 32% this year. Last month, B. Riley raised the firm's price target on Marvell to $115 from $110 and kept a buy rating on the shares following the company's custom AI investor webcast, according to The Fly. The firm said that it believes the update shows a "strong" next-generation AI growth inflection for Marvell. Turning to Apple, Versace noted that the computer giant's shares have been climbing recently, which is likely due to reports the company is weighing the benefits of using AI technology from Anthropic or OpenAI to power its long-awaited upgrade to Siri, rather than leaning on in-house solutions. Apple has had discussions with both companies about using their large language models for Siri, asking them to train versions that could run on Apple's cloud infrastructure for testing, Bloomberg reported, citing people familiar with the discussions. In March, Apple said AI improvements to its voice assistant Siri will be delayed until 2026, without giving a reason for the setback. Apple shook up its executive ranks to get its AI efforts back on track after months of delays, with Mike Rockwell taking charge of Siri, as CEO Tim Cook lost confidence in AI head John Giannandrea's ability to execute on product development, Bloomberg reported at the time. "We will want to see how this plays out, but should Apple decide to use one of those, it would likely accelerate the delivery of a more useful and smarter Siri," Versace said. "That would potentially charge up the iPhone upgrade cycle to newer models, a nice revenue driver for Apple." Related: Apple could make big change to Siri, delight fans Apple is scheduled to report third quarter results on July 31 and Versace said that, while the company is normally tight-lipped on its earnings calls, "odds are we will get some questions about this during the Q&A on its June quarter conference call." "We will be listening to see what is said," he said. Separately, Jefferies analyst Edison Lee upgraded Apple to hold from underperform with a price target of $188.32, up from $170.62. Counterpoint reported global iPhone's sales volume in April plus May was up 15% year-over-year, marking the strongest growth since Q3 of 2021. Tariff-driven pull-in demand and share recovery in China could drive June quarter revenue and EPS growth of about 8% and 10%, respectively, which would be roughly 5% and 9%, respectively, greater than consensus and greater than Apple's low-single digit revenue growth guidance, the analyst added while previewing fiscal Q3 results. While the market's benign view on tariffs is "likely overly optimistic," and Apple's service revenue has downside potential, Lee said, good Q3 results "could keep the stock stable" near-term. Meanwhile, Versace is tracking President Donald Trump's Big Beautiful Bill and the July 9 tariff deadline. "While we would like to see some of those uncertainties removed, the details for both will matter," he said. "Once we know them, we'll be better able to plot our moves."

Stripe's first employee, the founder of fintech Increase, sort of bought a bank
It's an open secret in the fintech world that the founder and CEO of startup Increase, Darragh Buckley, has been trying for years to 'buy a bank,' as one person familiar with the landscape told TechCrunch. A couple of weeks ago, he basically succeeded. He bought a big enough stake in Twin City Bank to trigger a public disclosure of the transaction by the Federal Research Board. Such share purchases are then subject to FDIC approval. Twin City is a small community bank in Longview, Washington, about an hour north of Portland, Oregon. The stake had to be in excess of 10% to trigger the disclosure. Buckley confirmed the deal to TechCrunch but declined to say how big of a stake he purchased. Whether he owns 11% or, say, 51%, we understand he is not the sole owner. Still, anything upwards of 10% makes him a major shareholder. (For comparison, public companies have to disclose all ownership stakes of 5% or more.) The assumption in the industry was that Buckley wanted a bank to further the ambitions of Increase, his banking-as-a-service (BaaS) startup, multiple sources told TechCrunch. What's particularly wild is that a mysterious entity — most likely one of Buckley's competitors — was so opposed to this deal that it hired an agency to pitch the press on writing negative stories about it and him. But, Buckley told TechCrunch, this was actually his third investment in a Washington community bank and his interests are not what his competitors think.

Boston, MA | REGISTER NOW This is not an effort for Increase to own the bank, he said. 'Twin City Bank is, and will remain, a community-focused bank,' he said. Silicon Valley finds a banking shortcut Increase offers an API platform that allows financial services to be programmatically served. It performs tasks like automated clearing house transactions, wires, real-time payments, etc. Increase's customers are largely other fintechs like Ramp, Check, and Pipe. As Stripe's first employee, Buckley has 'a great reputation as an engineer among his peers,' one person in the fintech industry told TechCrunch. Even some BaaS competitors refer business to Increase when they can't handle it themselves. Like most fintechs, Increase partners with (and shares revenue with) FDIC-insured banks to offer such regulated services. Obtaining banking licenses themselves is difficult and expensive. Even Chime, which offers checking and savings accounts and recently had an IPO, is not an FDIC-insured bank but has banking partners. In Increase's case, it works with Grasshopper Bank and First Internet Bank of Indiana. (Buckley said he has no personal investment in either one.) However, BaaS is a crowded, competitive market. That's led a small number of them to find a workaround to stand out: buying small community banks directly and doing away with banking partners. The biggest example of this is William Hockey, co-founder of Plaid, whose current fintech, Column, bought Northern California National Bank for $50 million in 2021. Another example is a Kansas City bank called Lead, bought and led by former Block executives Jackie Reses, Lead's CEO, and Ronak Vyas, CTO. The dangers of fintech partnerships Buckley insists he has no plans to turn Twin City into his company's personal partner bank or to swell its revenues with lots of fintech partners like Increase's customers. The latter, he knows, can be dangerous. For example, Evolve Bank, a partner to many fintechs from Affirm to Stripe, was the target of a large ransomware attack in 2024. This was shortly after the Federal Reserve System issued a cease-and-desist consent order to Evolve over problems it found with the bank's risk management systems. Evolve was ordered to implement pages of compliance fixes. (The bank was also associated with the meltdown of BaaS startup Synapse.) 'Twin City Bank shouldn't support sponsor banking,' Buckley explained, referring to banking partnerships with fintechs. 'Sponsor banking requires very specific capability and capacity to supervise partners safely and soundly. Only specialized banks should do it.' So why make such a big investment if not to benefit Increase? Because he likes community banks. They are the underdogs of the banking world. 'There's perhaps a prevalent view in the financial technology industry that community banks can't grow on their own. But community banks' strength is their relationships and knowledge,' he said. If Buckley's plan for the bank ever changes, his BaaS competitors will be watching. As for the mysterious entity hoping to stop him: it's too late. He said he received the FDIC's 'non-objection for control' approval and the deal has already closed.
